Abstract: The invention provides a system and method for providing media streams, the method include the steps of: receiving live media streams at a first path; providing a live media stream from the first path to a client, in response to a request to provide the live media stream to the client; and retrieving media related information and providing a non-live media stream from a second path to a client, in response to a request to provide the live media stream to the client.

Abstract: The invention provides a system and a method for synchronizing cable modems, the method includes the stages of: (i) generating, at a media access control entity, synchronization messages; and (ii) updating the synchronization messages to provide updated synchronization messages, whereas the updating is responsive to delays introduced at least during a stage of multiplexing the updated synchronization messages and additional content. The invention provides a system and a method of encrypting a data stream, the method includes the stages of: (i) receiving, at a multiplexing entity, at least one data stream destined to at least one cable modem; (ii) receiving, at the multiplexing entity, at least one encryption key generated by a cable modem termination system, whereas each encryption key is associated with at least one cable modem; and (iii) encrypting at least one data stream with at least one encryption key associated with the at least one cable modem.

Abstract: A system and method for modulating a service conveying stream to be transmitted over a medium, the method includes: (i) receiving a service conveying packet belonging to the service conveying stream; and (ii) determining at least one modulation parameter for the modulation of the service conveying packet in response to at least one network topology characteristic and in response to at least one client related parameter. The system includes input ports and a management entity capable of determining modulation parameters.

Abstract: Broadband multimedia system comprising a communication bus, a broad band multimedia router, connected to the communication bus, to a data router and further between a plurality of media sources and a plurality of network transmitters, a session manager, connected to communication bus, the session manager providing routing instructions to the router, for directing media received from the media sources to the network transmitters for transmitting over a broadband network and for directing data received from the router to at least a selected one of the network transmitter for transmitting over the broadband network to a specific destination.

Abstract: System and method for providing media packets to users, the end users coupled to a communication network having a communication network protocol, the method includes the steps of: (a) receiving non-addressable media packets; (b) blocking media packets of non-selected media streams; (c) converting non-addressable media packets of selected media streams to addressable media packets complying with transmission parameters and with specifications of the communication network protocol; and (d) routing the addressable media packets in response to selection signals received from the users.
